Patent abstract

A rugged, hand-held container for storing beverage containers is formed by folding together multiple panels defined in a pre-scored, slot-less blank. Each blank comprises a rectangular center panel integrally bordered by a pair of end panels and side panels. Integral, diametrically spaced apart corner panels interconnect the center panel with the other panels. Score lines between the adjacent panels facilitate folding. The center panel forms a cooler bottom, and blank end and side panels respectively form carton ends and sides. Each end panel has an outer locking panel comprising an elongated receptive slot. Each side panel has an integral outer handle panel comprising an inner roof segment that forms the container top and handle segments with locking tabs that are captivated within the receptive slot. A radiused locking tab ramp comprises an enlarged portion providing an overcenter action. Notches adjacent the tabs captivate the locking panels.
